Si838x Data Sheet Bipolar Digital Field Inputs for PLCs and Industrial I/O Modules KEY FEATURES The Si838x provides eight input channels ideal for 24 V digital logic commonly used for industrial applications. These channels can either sink or source current and feature integrated safety rated isolation. In combination with a few external components, this provides compliance to IEC 61131-2 switch types 1, 2, or 3. The input interface is based on Silicon Labs' ground-breaking CMOS based LED emulator technology which enables the bipolar capability (sinking or sourcing inputs) with no VDD required on the field side. The output interface from the Si838x device allows for low power operation with 2.25 V compliance. These products utilize Silicon Labs' proprietary CMOS-based isolation technology, supporting up to 2.5 kVRMS withstand voltage. This technology enables high CMTI (up to 300 kV/μs), lower propagation delays and channel skew, reduced variation with temperature and age, and tighter part-to-part matching. The Si838x offers longer service life and dramatically higher reliability compared to opto-coupled input solutions. • Bipolar digital interface with 24 V sinking or sourcing inputs • Eight total inputs in one package • High data rates of up to 2 Mbps • Safety rated integrated isolation of 2.5 kVRMS • Low input current of 1 mA typ • No VDD required on field side • High electromagnetic immunity • Selectable debounce filter times of up to 100 ms Product options include parallel or serialized outputs. Parallel outputs can be purchased with built-in, low-pass filters for improved noise immunity, reduced design complexity and cost. Cascading a total of 128 channels (16x Si838x) with a single MCU interface is possible with the Si8380S serial output option. The Si8380S also unlocks the ability to configure each channel with unique filtering behavior. • Configurable debounce filter modes available with SPI interface option • Transient immunity up to 300 kV/μs • Flow-through output configuration with eight outputs • Option for SPI interface with daisy-chain capability Safety Regulatory Approvals: • UL 1577 recognized • Up to 2500 VRMS for one minute Applications: • Programmable logic controllers • Industrial data acquisition • Distributed control systems • CNC machines • I/O modules • Motion control systems • Wide 2.25 to 5.5 V VDD operation • Wide operating temperature range • –40 to +125 °C • CSA component notice 5A approval • IEC 60950-1 • IEC 62368-1 • VDE certification conformity • VDE 0884-10 • CQC certification approval • GB4943.1 • Compliant to IEC 61131-2 • Type 1, 2, 3 • RoHS-compliant packages • QSOP-20 Si8380S Si8380P A1 1 20 B1 A1 1 e 19 B2 A2 2 e 18 B3 A3 3 17 B4 A4 4 16 VDD COM 5 15 GND COM 6 14 e e e 20 MISO e 19 MOSI e 18 NSS 17 SCLK 16 VDD 15 GND 14 MOSI_THRU e 13 NC NC NC 3 A4 4 COM 5 COM 6 A5 7 e B5 A5 7 A6 8 e 13 B6 A6 8 A7 9 e 12 B7 A7 9 e 12 A8 10 e 11 B8 A8 10 e 11 e silabs.com | Building a more connected world. e Isolation Barrier 2 A3 Isolation Barrier A2 SPI Rev. 1.0 Si838x Data Sheet Ordering Guide 1.

System Overview 2.1 Theory of Operation The operation of an Si838x channel is analogous to that of a bipolar opto-coupler, except an RF carrier is modulated instead of light. This simple architecture provides a robust isolated data path and requires no special considerations or initialization at start-up. A simplified block diagram for a single Si838x channel is shown in the figure below. HF Transmitter e Modulator Isolation Barrier Ax/AHx VDD Demodulator Debounce B BH Bx/BHx COM Figure 2.1. Simplified Channel Diagram This product enables 24 V bipolar digital inputs to be connected to its input through a resistor network which acts as a voltage divider. Other digital voltage levels and characteristics can be implemented with simple modifications to the resistor network. See 4.2 IEC 61131-2 Compliance Options for resistor network recommendations. The inputs can be sourcing or sinking type. To enable this functionality, there is a diode bridge and an LED emulator at the front end of each input channel that drives an OOK (On-Off Key) modulator/demodulator across the capacitive isolation barrier. See 3.3 Bipolar LED Emulator Input for details on the input channel. On the output side, the signal is either passed directly to the output stage in the case of a high-speed channel (BHx), or the signal is routed through a debounce filter block in the case of a low-speed channel (Bx). Thus, the high-speed channel offers the highest performance with the least propagation delay, but also the worst noise immunity. With the addition of the debounce filter block on the lowspeed channel, precise noise control can be achieved. The debounce block is configured by selecting the debounce filter mode applied and the amount of debounce filter delay time desired. There are three debounce filter modes available: deglitch filter mode, low-pass filter mode, and blanking filter mode. There are four debounce filter delay time options available: no delay, or delays of 10, 30, or 100 milliseconds. Additionally, a built-in low-pass filter delay of 4 µs is always present in low-speed channels, regardless of user configuration options. The desired filter delay time for parallel output devices can be selected by part number in 1. Ordering Guide. This filter delay time selection applies to all low-speed channels present on the device. The only filter mode available for parallel output interface devices is the low-pass filter mode. In addition to the parallel output interface options available on the Si838x, there is also a serial output interface option. The Si8380S offers a four wire SPI interface with an additional MOSI_THRU output to facilitate the cascading of up to 16 Si8380S devices. Using the SPI interface detailed in section 3.5 Serial Peripheral Interface, the debounce filter type and filter delay time can each be controlled on a per channel basis. The debounce filter modes are explained in detail in 3.6 Debounce Filter. silabs.com | Building a more connected world. Rev. 1.0 | 4 Si838x Data Sheet Device Operation 3. Device Operation Table 3.1. Truth Table Summary VDD Input, Ax/AHx Output, Bx/BHx P1 ON HIGH P OFF LOW UP2 X Undetermined3 1. P = powered (> UVLO). 2. UP = Unpowered (< UVLO). 3. An undetermined state can be any value within the absolute maximum rating of the output channel. See Table 5.10 Absolute Maximum Ratings1 on page 23 for details. 3.1 Device Behavior During any period in which VDD is below the UVLO threshold, such as device start-up, the output Bx/BHx is in an undetermined state until VDD is brought above the UVLO threshold for a time period of approximately tSTART, after which Bx/BHx is immediately pulled low. Following this, the output is high when the current flowing from anode to cathode in the LED emulator is > IF(ON). Note that there is a propagation delay time (tP) between a valid change on the input and a valid change on the output. Also note that there is a similar rise (tR) and fall (tF) time that should be accounted for in any valid change of the output. Finally, for low-speed channels, there is an additional filter delay time added to the propagation delay time. See Table 5.2 Electrical Characteristics on page 16 for detailed propagation delay specifications for all channel configurations, as well as specifications for all other timing parameters defined here. Device startup, normal operation, and shutdown behavior are shown in the figure below. VDDHYS VDDUV+ VDDUVVDD IHYS IF(TH) Ax/AHx tSTART Bx/BHx tP tP tP tSTART tP tP 90% 50% 10% tR tF Figure 3.1. Si838x Timing Diagram silabs.com | Building a more connected world. Rev. 1.0 | 5 Si838x Data Sheet Device Operation 3.2 Undervoltage Lockout Undervoltage Lockout (UVLO) is provided to prevent erroneous operation during device startup and shutdown or when VDD is below its specified operating range. During UVLO, the outputs from the device do not track the inputs to the device. For example, the device unconditionally enters UVLO when VDD falls below VDDUV– and exits UVLO when VDD rises above VDDUV+. During UVLO, the outputs are in an undetermined state and should be controlled using external components like a pull-up or pull-down resistor. See section 3.4.2 Output Pin Termination and State Control for circuit recommendations 3.3 Bipolar LED Emulator Input Each input channel on the Si838x can be modeled as a full bridge rectifier attached to an LED. A simplified equivalent circuit is depicted in Figure 3.2. Note that the model changes based on the whether the channel is sourcing or sinking current. The input current to the LED emulator is used to power the isolation channel transmitter and send the input signal across the isolation barrier. This eliminates the need for a power supply on the input side of the device. See section 2.1 Theory of Operation for a complete overview of the signal path through the device.
